Abstract

A plug connection for aquarium pressure medium conduits, particularly in combination with external aquarium filter devices. The connection comprises a plug, and a sleeve for receiving the plug. Both the plug and the sleeve are provided with a valve disc capable of blocking an associated conduit. Each valve disc is liftable from a sealing seat thereof against the force or biasing effect of a spring associated therewith. During plugging together of the plug and sleeve, axially displaceable shafts of the valve discs come into abutment with each other. The housing of the plug and the housing of the sleeve are capable of being plugged together in such a manner that a pressure-tight conduit is formed between the two valve discs.

Description

Die Erfindung betrifft eine Steckverbindung für Aquariendruckmittelleitungen, insbesondere in Verbindung mit Aquarienfiltereinrichtungen, mit einem Stecker und einer diesen aufnehmenden Muffe, wobei sowohl der Stecker als auch die Muffe mit einem die Leitung absperrenden Ventilteller versehen sind, der gegen die Wirkung einer Feder von seinem Sitz abhebbar ist und deren axial verschiebbare Schäfte beim Zusammenstecken des Steckers und der Muffe zum gegenseitigen Anschlag kommen, wobei die Gehäuse des Steckers und der Muffe derart zusammenführbarsind, daß sie zwischen den beidenVentiltellerneinedruckdichteLeitungbilden.The invention relates to a plug-in connection for aquarium pressure medium lines, in particular in connection with aquarium filter devices, with a plug and a receptacle which accommodates them, both the plug and the receptacle being provided with a valve disk which blocks the line and can be lifted off its seat against the action of a spring and whose axially displaceable shafts come to a mutual stop when the plug and the sleeve are plugged together, the housings of the plug and the sleeve being able to be brought together such that they form a pressure-tight line between the two valve disks.

Steckverbindungen für Druckmittelleitungen dieser Ausbildung sind bekannt (DE-C-32 998); bekannt sind weiterhin schlechthin Steckverbindungen für Wasser enthaltende Aquarienleitungen (DE-A-2 457 473).Plug connections for pressure medium lines of this training are known (DE-C-32 998); plug connections for water-containing aquarium lines are also known (DE-A-2 457 473).

Bei den bekannten Steckverbindungen für Druckmittelleitungen weist der Ventilteller auf seiner dem Schaft gegenüberliegenden hinteren Seite eine Stange auf, die von einer Druckfeder umschlossen und in einem in der Druckmittelleitung befindlichen Quersteg geführt ist, der eine nur geringe Breite und damit nur eine kurze Führungsfläche aufweist. Darüber hinaus befinden sich diese Führungsmittel in größerem Abstand von Ventilteller und den Dichtungsflächen. Damit besteht die Gefahr der Verkantung und eines unzureichenden Ventilschlusses.In the known plug connections for pressure medium lines, the valve disk has on its rear side opposite the shaft a rod which is enclosed by a pressure spring and is guided in a crossbar located in the pressure medium line, which has only a small width and thus only a short guide surface. In addition, these guide means are located at a greater distance from the valve plate and the sealing surfaces. There is therefore a risk of canting and insufficient valve closure.

Demgegenüber liegt der Erfindung die Aufgabe zugrunde, die Führung des Ventiltellers zu verbessern und Verkantungen sowie Mängel beim Ventilschluß auch dann auszuschließen, wenn Stecker und Muffe beim Herstellen und beim Lösen der Steckverbindung sich nicht in konzentrischer Lage befinden.In contrast, the invention has for its object to improve the guidance of the valve plate and exclude canting and defects in valve closure even if the connector and sleeve are not in a concentric position when making and loosening the connector.

Zur Lösung dieser Aufgabe haben erfindungsgemäß der Ventilteller und sein Schaft eine zentrale Bohrung, die auch den Ventilteller durchdringt, wobei in die Bohrung ein am Gehäuse gelagerter Zapfen in der Weise eingreift, daß der Ventilteller und der Schaft längsgeführt sind, und zudem umschließt die Ventilfeder den Zapfen.To solve this problem, the valve plate and its stem have a central bore, which also penetrates the valve plate, wherein a pin mounted on the housing engages in the bore in such a way that the valve plate and the stem are guided longitudinally, and in addition the valve spring encloses the Cones.

Demgemäß erfolgt die Führung des Ventiltellers und seines Schaftes durch einen Zapfen, der eine lange Führungsfläche hat und nicht nur den Ventilteller, sondern auch seinen frei nach vorne gerichteten Schaft durchsetzt und in gehöriger Weise zu führen imstande ist. Demgemäß können beim Zusammenführen und Lösen von Stekker und Muffe auf die Schäfte einwirkende Schrägkräfte nicht zu Verklemmungen und Verkantungen des Ventiltellers führen, vielmehr ist auch unter diesen Bedingungen ein ordnungsgemäßes Öffnen und Schließen der beiden Ventile sichergestellt.Accordingly, the valve plate and its stem are guided by a pin which has a long guide surface and which not only penetrates the valve plate but also its freely directed stem and is capable of being guided in a proper manner. Accordingly, when the connector and sleeve are brought together and released, inclined forces acting on the shafts cannot lead to jamming and tilting of the valve plate; rather, proper opening and closing of the two valves is ensured even under these conditions.

Ein Ausführungsbeispiel der Erfindung ist in der Zeichnung dargestellt.An embodiment of the invention is shown in the drawing.

Die Abbildung zeigt einen senkrechten Schnitt durch einen Winkelstecker und eine zugehörige Muffe, und zwar übereinanderliegend in fluchtender Stellung.The illustration shows a vertical section through an angled plug and an associated socket, one above the other in the aligned position.

Der oben dargestellte Winkelstecker 1 hat an seinem hinteren oberen Teil eine waagerecht abstehende Tülle 2 zur Aufnahme eines Schlauches 3, der zu einer innerhalb des Aquariums befindlichen Druckpumpe führt.The angled plug 1 shown above has at its rear upper part a horizontally projecting spout 2 for receiving a hose 3 which leads to a pressure pump located inside the aquarium.

Die Muffe 4 ist hingegen in eine Wandung 5 eines druckfesten Filtergehäuses eingesetzt.In contrast, the sleeve 4 is inserted into a wall 5 of a pressure-resistant filter housing.

Die Muffe 4 und der Stecker 1 haben nach unten bzw. nach oben gerichtete Zapfen 6, die koaxial zu den beiden vorne im wesentlichen rohrförmigen Gehäusen 7 angeordnet sind. Der Zapfen 6 des Steckers 1 ist dabei an der oberen Querwand 8 des Gehäuses 7 befestigt. Der Zapfen 6 der Muffe 4 ist an einem Käfig 9 gelagert, der aus Armen 10 zum Durchtritt des Wassers gebildet ist.The sleeve 4 and the plug 1 have downward or upward directed pins 6, which are arranged coaxially to the two front tubular housings 7. The pin 6 of the plug 1 is attached to the upper transverse wall 8 of the housing 7. The pin 6 of the sleeve 4 is mounted on a cage 9, which is formed from arms 10 for the passage of water.

An den Zapfen 6 sind die dem Stecker 1 und der Muffe 4 zugeordneten Ventilteller 11 mit Bohrung 12 und die zugehörigen hohl gehaltenen Schäfte 13 iängsgeführt.On the pin 6 the valve plate 11 associated with the plug 1 and the sleeve 4 with bore 12 and the associated hollow shafts 13 are guided longitudinally.

Die auf den Zapfen 6 befindlichen Druckfedern 14 wirken auf die Ventilteller 11 in der Weise ein, daß sie mit ihrer schrägen Sitzfläche 15 gegen einen Dichtungsring 16 angepreßt werden, der sich in einer Ringnut 17 des Gehäuses 7 befindet. Die Druckfedern 14 sorgen also für den Ventilschluß. Der Durchgang für das Wasser ist also nicht möglich, wenn Muffe 4 und Stecker 1 getrennt sind.The compression springs 14 located on the pin 6 act on the valve plate 11 in such a way that they are pressed with their oblique seat surface 15 against a sealing ring 16 which is located in an annular groove 17 of the housing 7. The compression springs 14 thus ensure the valve closure. The passage for the water is therefore not possible if socket 4 and connector 1 are separated.

Der Schaft 13 des Steckers 1 ist an seinem freien Ende kegelig gehalten; das freie Ende des Schaftes 13 der Muffe 4 hat eine entsprechende kegelige Ausnehmung 18. Darüber hinaus springt das freie Ende des Schaftes 13 des Stekkers 1 gegenüber dem Gehäuse 7 vor, und zwar um ein Maß a. Die Länge des Schaftes 13 der Muffe 4 ist dabei so bemessen, daß beim Zusammenführen des Steckers 1 und der Muffe 4 die kegelige Spitze 19 des Schaftes 13 ganzflächig in der Ausnehmung 18 zur Anlage kommt, nachdem bereits die außen am freien Gehäuseende befindliche Dichtung 20 des Steckers 1 an der Innenfläche 21 der Muffe 4 zur Anlage gekommen ist. Erst nachdem dieser Dichtungsschluß zustande gekommen ist, verschieben sich beim weiteren Zusammenstecken der Muffe 4 und des Steckers 1 die Schäfte 13 gegen die Federkraft. Das damit stattfindende Abheben der Ventilteller 11 und Öffnen der Ventile geschieht also erst nach Bildung eines druckdichten Durchganges durch die einander zugekehrten rohrförmigen Teile des Gehäuses 7. Im zusammengesteckten Zustand liegt dann die Stirnfläche 22 des Stekkers 1 auf dem Absatz 23 der Muffe 4 auf.The shaft 13 of the plug 1 is tapered at its free end; the free end of the shaft 13 of the sleeve 4 has a corresponding tapered recess 18. In addition, the free end of the shaft 13 of the plug 1 protrudes relative to the housing 7 by a dimension a. The length of the shaft 13 of the sleeve 4 is dimensioned such that when the connector 1 and the sleeve 4 are brought together, the conical tip 19 of the shaft 13 comes to rest over the entire surface in the recess 18 after the seal 20 of the outside of the free housing end Plug 1 has come to bear on the inner surface 21 of the sleeve 4. Only after this seal has come about, when the sleeve 4 and the plug 1 are plugged further together, do the shafts 13 move against the spring force. The taking off of the valve plate 11 and opening of the valves thus takes place only after the formation of a pressure-tight passage through the mutually facing tubular parts of the housing 7. In the assembled state, the end face 22 of the plug 1 then lies on the shoulder 23 of the sleeve 4.

Zum Lösen der Verbindung z. B. zum Zwecke der Reinigung des Filters wird der Stecker 1 gezogen. Dabei schließen die Ventile unter der Federkraft. Dies geschieht wiederum vor einer Trennung der beiden Teile 1,4.To release the connection z. B. for the purpose of cleaning the filter, the plug 1 is pulled. The valves close under the spring force. This again occurs before the two parts 1, 4 are separated.
